        Hi there,

        I have a conventional floor standing Baxi boiler that has developed an air-lock after the system was drained and refilled without the motorised valve being set on manually.

        I have tried all kinds to remove the air … bleeding gallons of water out of each radiator … allowing system to flush through with the boiler and pump on … but nothing seems to work.

        The boiler fires up from cold, but quickly heats whatever water is in it, and then shuts off.

        Have you any advise as to how I can remove the air from the system. The boiler is definately working ok, as it is continually fired up if I allow the system
        to continually flush through.

        Regards

        Rod Wilson

          Perhaps the system is not air-locked. Make sure your circulator is working. sometimes with these new compact circulators it is difficult to be sure. Having power to the circulator is no guarantee it is operating.
